Abstract
An ink jet recording method is capable of suppressing generation of image streaks and recording a high-quality image when using a recording apparatus equipped with a line head. The ink jet recording method records an image on a recording medium by using an ink jet recording apparatus equipped with a line head. In this method, the line head has a plurality of recording element substrates each having a nozzle array made up of a plurality of nozzles which eject an aqueous ink. The recording element substrates are arranged in a predetermined direction. An average temperature Te (° C.) of the aqueous ink ejected from terminal-portion nozzles constituting the terminal portions of the nozzle arrays and an average temperature Tc (° C.) of the aqueous ink ejected from center-portion nozzles constituting the center portions of the nozzle arrays satisfy the following relationship: Te>Tc.
